Increased mtPDH activity through antisense inhibition of mitochondrial pyruvate dehydrogenase kinase enhances inflorescence initiation, and inflorescence growth and harvest index at elevated CO2 in Arabidopsis thaliana

Increased mtPDH activity through antisense inhibition of mitochondrial pyruvate dehydrogenase kinase enhances inflorescence initiation, and inflorescence growth and harvest index at elevated CO2 in Arabidopsis thaliana

Mitochondrial pyruvate dehydrogenase (mtPDH) is a key respiratory enzyme that links glycolysis and the tricarboxylic acid cycle, and it is negatively regulated by mtPDH kinase (mtPDHK). Arabidopsis lines carrying either a constitutive or seed-specific antisense construct for mtPDHK were used to tes...
